"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nspi: fix statistics allocation\n\nThe controller per-cpu statistics is not allocated until after the\ncontroller has been registered with driver core, which leaves a window\nwhere accessing the sysfs attributes can trigger a NULL-pointer\ndereference.\n\nFix this by moving the statistics allocation to controller allocation\nwhile tying its lifetime to that of the controller (rather than using\nimplicit devres)."
